THREAD-GUARD FOR RING-SPINNING FRAMES.

SPECIFICATION forming part ofLetters Patent No. 279,798, dated June 19,18 83.

Application filed January 20, 1883. (No model.) i

' River, in the county of Bristol and State of Massachusetts, haveinvented certain new and useful Improvements in Thread-Guards for BingSpinning Frames; and I do hereby declare that the following is afull,clear, and exact description of the invention, which will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, which form apart of this specification, and in which- Figure 1 is a front elevationof so much of a ring-spinning frame as is requisite to illustrate myinvention. Fig. 2 is a rear view of the same. Fig. 3 is a transversevertical sec tion thereof, taken between two next adjacent rings of thering-rail, showing in side'elevation one of my improved thread-guardswith its latch. Fig. 4 is a perspective detail view of the thread-guarddetached; and Fig. 5 is a sectional detail view, showing the manner ormeans of fastening the guard to its shaft.

Like letters of reference indicate correspond ing parts in all thefigures.

My invention has relation to thread-guards for ring-spinning frames; andit consists in certain improvements upon the thread-guard for whichLetters Patent No. 269, 231 were granted to me on December 19, 1882,which said improvements will be hereinafter more fully de scribed andclaimed.

In the accompanying drawings, A A A de note the spindles, B B B theirbobbins, O and D the spindle-supporting rails, and E the ring-rail, allof which may be constructed and applied in any well-known manner. Abovethe ring-rail, journaled in boxes; f, carried by uprights or brackets F,secured to the rear of the ring-rail, is a shaft, G, which is parallelto the rail, and runs its entire length from end to end. Fa-stened uponthis shaft G are the threadguards, the outer ends of which formflattened heads H, which project, when the guards are in use, in ahorizontal plane between each adjacent pair of bobbins, and at rightangles thereto, as clearly shown in the drawings. This flat part or headis re-enforced by a rib or feather, 71, on the under side, which formsan extension of the shank H, the inner end of the guard to the shaft inthe following manner:

Shaft G is flattened lengthwise on one side, as

.shown at g, and boX H of the guard has alip,

1', adapted to fit said flattened part of the shaft, thus preventing theguard from turning on the shaft. It is fastened thereon by a screw, S,the head 8 of which bears against the shaft, operating to clamp box Hupon the shaft, so as to hold the thread-guard firmly in its place uponthe shaft when the screw is itightened down. At the same time the guardcan readily be removed by simply loosening the screw, so that the shaftitself need not to be interfered with when it is desired to remove oneor more ofthe guards. The guards are kept in their proper workingposition by means of a latch or hinged support, I, the upper end ofwhich is hinged upon the side of any one of the threadguards in theseries, while its free lower end is bent to form a catch, I, adapted toengage a lip, e, on the corresponding bracket or shaftsupport, F. Bydisengaging the free end of the latch the guards will of their ownweight drop with their free ends upon the ring-rail between two nextadjacent bobbins, as indicated on Fig. 3 of the drawings by dottedlines, so as to be out of the way of the attendant while he may bedoffing the bobbins.

By this construction and arrangement of the thread-guards there is lessdanger of their getting broken than when the guards are swung back fromthe ringrail to get them out of the way, as described in my LettersPatent No. 269,231, of December 19, 1882, because when the guards areturned back while the machine is running there is danger of theirstriking against the roller-beams or other parts of the machine. Anotherimportant advantage of this construction is that by dropping the freeend of the thrcad-guard upon the ring-rail, in stead of back of thesame, it will keep the weight of the dropped guard 011 about the middleof the rail instead of to one side of it, so

' that by my improved construction and arrangement the rail will beevenly balanced. By constructing the thread-guards with flatheads H, setat right angles to the spindles, they can be set nearer to the ringsthan if made with wedgeshaped heads, asin my Patent No. 269,231,.

waves 2. Thethread-guards consisting ofthe flattened head H, shank H,having central rib, h, and box H having lip i, flattened on the inside,all in one piece, substantially as and for the purpose shown and setforth.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.
